Abstract
The utility model discloses a low-pressure casting mold which comprises a crucible, a riser tube, an air inlet tube, a sealing cover, a pouring gate, a cavity and a casting mold. The casting mold is provided with the cavity, one side of the cavity is provided with the pouring gate, the riser tube is arranged in the crucible, the sealing cover is arranged at the middle position between the casting mold and the crucible, and the air inlet tube is arranged at the middle position between the sealing cover and the crucible. Due to the fact that molten metal is filled under the action of pressure, the mold-filling capacity is improved, a casting part with a clear outline can be obtained, and the yield rate is high. Therefore, the mold enables the molten metal to be stably filled in the mold-filling process, the molten metal solidifies under the action of the pressure, and feeding is full, so that the casting part is compact in texture and high in mechanical property, and tensile strength and hardness are improved by about 10% compared with traditional gravitational casting molds.
Description
Technical field
The utility model relates to a kind of low pressure casting die.
Background technology
Low pressure casting has the stock utilization height, advantages such as soup automation are annotated in realization easily; With the automobile component is the center; Progressively established the firm status of the main casting of light alloy casting, but existing low pressure casting die make easily liquid metal filling steadily and mold-filling capacity not high.
The utility model content
The utility model purpose: in order to overcome the deficiency that exists in the prior art, it is steady that the utility model proposes a kind of liquid metal filling, and mold-filling capacity is good, the low pressure casting die that feeding is abundant, yield rate is high.
Technical scheme: for solving the problems of the technologies described above, the utility model proposes a kind of low pressure casting die, and it comprises: crucible, stalk, air inlet pipe; Seal cover, running channel, die cavity and casting mold; Be provided with die cavity in the described casting mold, a side of die cavity is provided with running channel, is provided with stalk in the described crucible; The middle of described casting mold and crucible is provided with seal cover, and the middle of seal cover and crucible is provided with air inlet pipe.
Described stalk, die cavity and casting mold link to each other successively.
Be provided with molten metal in the described crucible.
Beneficial effect: a kind of low pressure casting die that the utility model adopted through utilizing the driving force of filling casting mold, makes molten metal along flowing with the gravity rightabout; After waiting to get into the molten metal cooling in the die cavity, not solidified molten metal falls back in the crucible, compares with traditional casting mould; Practiced thrift cost, it is steady that this mould makes molten metal in cavity filling process, fill type, because of molten metal is the effect lower charging type at pressure; Therefore, mold-filling capacity improves, and helps obtaining the foundry goods of clear-cut; And yield rate is high, and because of molten metal is under the effect of pressure, to solidify, feeding is abundant; So THE STRUCTURE OF CASTINGS is fine and close, mechanical property is high, and tensile strength is compared with traditional gravity casting die with hardness and improved about 10%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the described a kind of low pressure casting die of the utility model comprises: crucible 1, stalk 2, air inlet pipe 3, seal cover 4, running channel 5, die cavity 6 and casting mold 7.
Be provided with die cavity 6 in the described casting mold 7, a side of die cavity 6 is provided with running channel 5, is provided with stalk 2 in the described crucible 1, and the middle of described casting mold 7 and crucible 1 is provided with seal cover 4, and the middle of seal cover 4 and crucible 1 is provided with air inlet pipe 3.
Described stalk 2, die cavity 6 link to each other with casting mold 7 successively.
Be provided with molten metal 8 in the described crucible 1.
The compressed air feeding of drying is equipped with in the airtight container crucible 1 of molten metal 8, acts on molten metal 8 liquid levels that keep constant temperature, make molten metal 8 get into die cavities 6 through running channel 5 from bottom to up along stalk 2; After band molten metal 8 is full of die cavity 6, increase air pressure, make molten metal 8 solidification forming under the effect of pressure in the die cavity 6; Remove the gas pressure on the liquid level then; Make that not solidified molten metal 8 falls back in the crucible 1 in the stalk 2, open casting mold again, take out foundry goods.
This low pressure casting die is through utilizing the driving force of filling casting mold, makes molten metal along flowing with the gravity rightabout, wait to get into the molten metal cooling in the die cavity after, not solidified molten metal falls back in the crucible; Compare with traditional casting mould, practiced thrift cost, it is steady that this mould makes molten metal in cavity filling process, fill type, because of molten metal is the effect lower charging type at pressure; Therefore, mold-filling capacity improves, and helps obtaining the foundry goods of clear-cut; And yield rate is high, and because of molten metal is under the effect of pressure, to solidify, feeding is abundant; So THE STRUCTURE OF CASTINGS is fine and close, mechanical property is high, and tensile strength is compared with traditional gravity casting die with hardness and improved about 10%.
The foregoing description only for the explanation the utility model technical conceive and characteristics, its objective is let be familiar with these those skilled in the art can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
